摘　　要：以工具电极形状及层深稳定为目标,研究了大分层厚度电火花轮廓铣削加工时步距与工具电极形状建立过程的内在关系,分析了步距量对工具电极形状控制的影响规律。结果表明,步距量与电极定形长度具有一定的线性关系,并且电极相对损耗率约是线性补偿量的4.359倍。研究成果为实现工具电极控形提供了一定的依据。This article aims to stabilize the shape and depth of the tool electrode.The internal relationship between the step length and the tool electrode shape establishment process during the machining of large layer thickness EDM contour milling is studied.The influence of step amount on the tool electrode shape and process allowance is analyzed.It is shown that there is a certain linear relation between the step amount and the fixed shape length of the electrode.And the electrode relative loss rate is about 4.359 times of the linear compensation amount.The research results provide some basis for the control of tool electrode.
